I decided to build roller-bearing slides instead of commercially available slides. This should provide years of solid use! 1" square tubing was bolted to the drawer sides to run between these bearings.
I want to incorporate/fuse this idea with the basic principles of a steamer chest or carpenter's toolbox. Have the big drawer that slid out open outward to create an L-shape with fold up legs to support it and staircase trays open up to create shelves. Boom! full size bar.
